AIR-MIXING A '.l."1 AGH1ll[E1 l".l FOR CARBURETERS.

Specification of Letters Patent.

Patented Nov. 19, 1912.

Application filed May 13, 1912. Serial No. 696,984.

To all whom 'it may concern:

Be it known that I, ELBERT C. PEGK, a citizen of the United States, residing at San Bernardino, in the county of San Bernardino and State of California, have in vented certain new and useful Improvements in Air-Mixing Attachments for Car: bureters, of which the following is a specification. v The invention relates to devices for mixing the explosive charge in internal combus tion engines and has for its object the proing proportioned to the speed of the engine'to prevent the mixture from becoming too rich and for that reason Wasting the fuel.

The invention consists of the combination with the throttle valve rod, of a valve operated by the rotation of the throttle valve rod to control the amount of air entering the conveyer duct from the fcarbureter to accomplish the purpose stated.

My invention will be described in detail hereinafter and illustrated in the accompanying drawings, in which,

Figure 1 is a side view partly in section of a conventional carbureter and conveyer duct showing my improved air inspirator in position thereon; Fig. 2, a longitudinal sectional view of the inspirator; and Fig. 3,

a detail view of the connection between the throttle valve rod and the air valve.

In the drawings similar reference characters will be used to designate corresponding parts throughout the several views.

Aindicates a carbureter of conventional type having the oil supply pipe B and the air inlet C connected therewith, D indicating the supply duct from the carbureter to the engine (not shown).

E indicates the throttle valve rod that controls the amount of explosive'mixture passing from the carbureter A into the-supply duct D.

As stated, my improved inspirator provides for supplying atmospheric air to the mixture passing through the duct after leaving the carbureter A, the amount being controlled by'the position of the throttle valve rod E and consisting of a pipe 1 tapped intothe duct D as shown at 2 and having a perforated distributer nozzle 3 on its end within the duct D.

4.indicates a pipe secured on the casing of the carbureter A by means of-a suitable clamp 5 and coupled to the pipe 1 by means of the coupling sleeve 6.. The pipe 4 is provided with an opening 6' adjacent to its terminal and has rotatably mounted on said terminal a closed sleeve 7 provided with an opening 8 that is adapted to register at times with the opening 6 aforesaid. The throttle valve E has a collar 9 adjust-ably secured thereon by means of a set screw 10, and the collar 9 is provided with a laterally extending arm ll'that is connected with a laterally extending arm 12 on the sleeve 7 by means of a link 13.

From this construction, it will be appar- I the supply duct D, so that as the speed of the englne increases, the amount of atmospheric air admitted into the pipes a and 1 to be supplied to the explosive mixture in the pipe B, will be increased to revent the mixture from becoming too rich'in the relative proportion of fuel to air for proper explosion's in the enginecylinders.

To insure a prompt return of the sleeve 7 to the position by which the opening 8 is out of register with the opening 6 when the throttle valve rod is rotated to close the throttle valve, I provide a spring 14 mounted on the pipe 4 and having one end secured in the end of said sleeve as shown at 15,

and its other end secured to a collar 16 that is adjustably secured to the pipe I} by means of a set screw 17.

Having thus described my invention, What I claim is 1. In combination with a carbureter, a duct for conveying the explosive mixture from said carbureter, and a throttle valve rod, a pipe having a distributer nozzle secured thereto and located within said supply duct, a ,valve rotatably mounted on said pipe to admit air thereto, and means actuated by thethrottle valve rod to operate said valve.

2. In combination with a carbureter, a supply duct leading therefrom, and a throttle valve rod, a pipe for supplying air to said supply duct, a perforated distributer nozzle on one end of said pipe and tapped into the supply duct, the other end of said supply pipe having an opening therein, a

sleeve rotatably mounted on said pipe and having an opening therein adapted to register with the opening in the plpe, an arm secured to the throttle valve rod, an arm secured to said sleeve, and a link connecting said arms.

3. In combination with a carbureter, a supply duct leading from said carbureter, and a throttle valve rod, a pipe mounted on the carbureter casing, said pipe being tapped into the supply duct and having a perforated distributer nozzle on its end within the supply duct, the other end of said pipe having an openingtherein, a sleeve rotatably mounted on said end of the pipe and having an opening therein adapted to regisuer with the opening in the pipe, a collar secured to the pipe, a coiled spring secured to said sleeve and collar, an arm secured to the throttle valve rod. an arm secured to said sleeve, and a link connecting said arms.

In testimony whereof I afiix my signature in presence of two witnesses.

ELBERT C. PECK.
